GLUING ATTACHMENT FOR lVlATCHlNG-MACHlNES.

SPECIFICATION forming part of Letters Patent No. 474,092, dated May 3, 1892.

Application filed October 26, 1891. Serial No. 409.888. (No model.)

To all whom it may concern.-

Be it known that l, BENJAMIN G. LUTHER, a citizen of the United States, residing at Worcester, in the State of Massachusetts, have invented a new and useful Improvement in Gluing Attachments for lVlatching-Machines, of which the following is a specification.

My invention consists in the improved construction and arrangement of the glue-distributing roller, as hereinafter fully set forth.

Figure 1 represents a top view showing the cutter and the feed-rollers of the matchinginachine. Fig. 2 represents a longitudinal vertical section taken in the line a 2 of Fig. 1. Fig. 3 represents a transverse vertical section taken in the line x m of Fig. 2. Fig. 4 repre sents a top view of the table for holding the glue-pot. Fig. 5 represents a top view of the glue-pot. Fig. 6 represents an edge View of the cover for the glue-pot and a side elevation of the glue-distributing wheel. Fig. 7 represents an edge view of the glue-distributing wheel. Fig. 8 represents a sectional View of the same. Fig. 9 is a detail section showing the action of the tongue of the board upon the flexible flaps of the glue-distributing wheel.

In the accompanying drawings, A represents the frame of the matching-machine, B B the feed-rollers, and G the cutter. The table D is removably held upon the upwardlyprojecting studs a, which enter the holes I) in the ears 0 of the table, and to the car 01 at the bottom of the hot-water dish e, formed in the table, is attached the brace f.-

Within the cavity got the dish 6, into which steam is caused to enter through the pipe 10, is placed the glue-pot h, thus forming the heating-chambero, and the cover 2' of the gluepot is provided with a slot j and with the downwardly-projecting ears 7.0 It, the said ears being provided with an open slot m, adapted to receive the shaft 01 of the glue-distributing wheel 0, the said wheel being held in its upward position by means of opposite springs 19, which press upward against the shaft n. The wheel 0 is provided with a circumferential groove g, which is adapted to receive the tongue r of the board 8, as shown in Fig. 9, and to the top of the flanges t of the wheel 0 are attached the flaps u, made of felt or similar flexible material, adapted to be bent downward into the groove g at each side of the tongue 7' to apply glue to the same, the said flaps being preferably made in scalloped form, as shown in Fig. 7, whereby the glue will be deposited in alternate patches upon the opposite sides of the tongue. TVhen the board is passed between the feed-rollers B B and forced forward over the cutter C, the tongue of the board will press down the flaps u and cause the rotation of the wheel 0 in the melted glue in the pot h, thus causing the deposit of the glue in alternate patches upon the opposite sides of the tongue 7' preparatory to uniting the tongued and grooved boards to each other as fast as they can be passed through the machine.

I claim as my invention 1. A glue-distributing Wheel provided with a circumferential groove adapted to receive the tongue and the projecting flexible covering for applying the glue to the side of the tongue as the edge of the board passes over the wheel, substantially as described.

2. A glue-distributii'ig wheel provided with a circumferential groove adapted to receive the tongue, the projecting flexible covering, and yielding means for supporting the said wheel against the edge of the board,substantially as described.

3. The combination, with the cutter and the feed-rolls of a matching-machine, of the glue-distributin g wheel provided with the circumferential groove adapted to receive the tongue and the projecting flexible covering for applying the glue to the side of the tongue as the edge of the board passes over and rotates the wheel, substantially as described.

4.. The combination, with the cutter and the feed-rolls of a matching-machine, of the gluepot, a glue-distributing wheel, and yielding means for holding the wheel against the edge of the board, so as to be rotated thereby, sub stantially as described.

BENJAMIN G. LUTHER.
